System and method to simulate and manage a wireless local area network (WLAN)

Abstract

In accordance with one embodiment, an article of manufacture embodied in a computer-readable medium for use in a processing system for modeling configurations of a wireless local area network is provided. The article of manufacture includes a characteristic and configurations receiving logic for causing the processing system to determine a set of original characteristics and configurations of the wireless local area network. As well, a simulation logic for causing the processing system to simulate an outcome based upon a set of configurations in accordance with a goal. In other embodiments, the goal may be user defined or based upon historical data. Further, a configuration creation logic for causing the processing system to create a set of new configurations based upon the outcome and a management logic for causing the processing system to apply the set of new configurations to the wireless local area network are provided.

Description

BACKGROUND OF THE ART [0001] Computer and telecommunication networks, specifically wireless networks, have grown in size and complexity. Both of these factors have caused network designers, operators, and users to rely on modeling software to assist them in simulating network configurations to optimize performance. Conventionally, network simulations have been used to evaluate performance of network configurations under defined traffic conditions. Performance includes such objective criteria as response time, throughput, and costs of transmissions. [0002] Recently, the focus of network trends have turned to the wireless local area networks (WLANs). As the popularity of WLANs continues to increase, the deployment density of IEEE 802.11 access points (APs) and the number of client stations has also increased. [0003] This overall increase of IEEE 802.11 radios brings about new challenges for the administrator of an IEEE 802.11 network. Without proper tools, managing the radio environme...

Computer and telecommunication networks, specifically wireless networks, have grown in size and complexity.

This overall increase of IEEE 802.11 radios brings about new challenges for the administrator of an IEEE 802.11 network.

Without proper tools, managing the radio environment of an IEEE 802.11 network becomes very difficult.

Administrators are plagued with the problem of effectively deploying WLANs and subsequently managing the network in the face of other radio interference, as well as IEEE 802.11 network congestion.

In order to accomplish this, the administrator today must employ expensive site surveys prior to deployment in combination with costly monitoring tools and personnel expenses used to maintain the network.

Even after providing expensive site surveys, the administrator is still plagued with a slow detection of radio network problems and substandard means of making radio network additions or modifications.

Essentially, the optimization of a WLAN is a complex problem.

The required timeliness to tune the performance of a WLAN to an optimum is very short.

Although unmanaged and non-optimized WLAN deployments may provide basic functionality, the user experience may greatly erode with the introduction of new wireless traffic.

In this example, in order to achieve acceptable audio quality in WVOIP, problems may occur in that the WLAN may not be able to handle the
